Clear Temporary Blocks With cPHulk
cPHulk is a security feature that locks down the cPanel/WHM logins, SSH, FTP, and IMAP/POP3 logins. These core services are locked down after too many fails from a single IP address. The lockout starts at whatever interval is set within the Configuration Settings panel and lasts for as long as defined in the IP Address-based Brute Force Protection Period field. You can also set blacklists and whitelists for IP ranges that you know will require special treatment.
You can learn more about the features of cPHulk at:
3. Go to Home » Security Center » cPHulk Brute Force Protection
4. Click on History Reports
5. Search for the IP address that your client has given you. In most modern web browsers you can search for text on the page by pressing Ctrl+F (Windows) or Command+F (Macintosh).
The search results will show you the last set of blocks that occured for that IP address. Make a note as to when the blocks occured and the type of block. This way you can help your client determine why they got blocked and what passwords they need to reset to prevent the block from occuring again.
6. Click on the Clear Data for All Reports button to remove all the current blocks.
